I recently invested in double glazing. First I noticed the kitchen wall was very wet -almost like sweet. Now ALL the external walls especially the corners have grown with black mould. Its lines with wall paper. When I removed some, even the bits not yet showing have mould. How do I tackle this. It is major. Will a typical home insurance cover this or is it possible to get a grant of some sort. I am a lady and not too good at DIY. I already had my fingers burnt recently when I got someone to put a new bathroom and it turned out he was a novice. Could this problem be related to the bathroom change too?

Hi
It is more than likely that this damp has been caused by one of the new jobs you have had done, due to you not experiencing this problem before.
Pvc door and winows are that well installed now that they do prevent allot of circulation of air. But i can't see this been related.
I would be more inclinded to get a good qualified plumber to check the work that has been carried out by your plumber to see if any pipes are leaking.
You will have to contact your insurance company direct to see what they cover.

Hallo, have a look at my posting on April 7th. You might just have the same problems that I had. Wet walls around a newly-installed window doesn't sound like plumbing to me! Alvin Wyllie

[quote="fumken"]Thanks. I think it may be condensation, from what I have now been told. I am thinking of calling the D/Glazing people to put in vents.[/quote]
Mmmm. Condensation on its own wouldn't cause wet walls. When I investigated the problem I had, I opened a window and poured water from a small watering can into the bottom of the frame, which will have holes to let rainwater escape out the front of the frame which it must do or else the water will go down in the brickwork and then you'll get wet walls, which is what I suspect is happening in your case. Have fun!

Your right with the condensation. And yes, it can wet a wall to a point where water droplets form.

The key here is to improve the ventilation. i.e remove moisture filled air. No need to go to the expense of putting vents in the already fitted windows, just open them and often. twice a day should do it.

with you installing double glazing you restrict air flow if the problem carries on id say look at a positive air unit this takes air from the loft area and circulates it around the whole hosue stop condensation from forming on the walls cost wise about Â£500.00 fully installed
